The reason why the protection pipe 31 is installed in this way is that the fluid pipe 32 can be easily replaced because it is not directly buried in the concrete wall, and the fluid pipe 32 for hot water and water This is to prevent water from leaking into the concrete wall if water leaks from the concrete wall.

Further, at the upper rear side of the protective tube fixture 1, a holding portion 14 having a through hole 15 passing through in the lateral direction is provided. As shown in FIGS. 4 and below, the support tube reinforcement 41 provided in the concrete wall 40 or the crossbar member 42 installed on the support support 41 is inserted into the through hole 15, and the protective tube fixture 1 is placed in a predetermined position. It is designed to be securely fixed.

Next, the pulling ring 2 has a female thread 21 on the outside that is screwed into the male thread 12 of the fluid socket attachment opening 11 of the protection tube fixture 1, and furthermore, as shown in FIG. It has a structure in which a screw hole 22, which is a locking part, is provided on the inside to be screwed into a bolt 4, which is a drawing member that is inserted from the outside.

The structure of the locking part is, for example, as shown in FIG. , a structure may be adopted in which a pulling member is formed of a hooking rod 9 having one end shaped like a key, and the one end of the hooking rod 9 is hooked on the rod 25 in the hole 23 to be locked, and the locking means is as follows. No question.

In addition, 24 is a recess for removing the pulling ring 2 from the fluid socket attachment opening 11 of the protective tube fixture 1 after it is buried in concrete, and it can be removed using a tool or the like having a protrusion that fits into the recess 24. The pulling ring 2 can be rotated and removed.

Now, we will explain the installation work of a fluid pot on a concrete wall using such a concrete buried object.
